He asked the Prophet ﷺ about the earnings of a cupper he owned, and the Prophet forbade him from it. He kept pressing him about it until the Prophet said, "Feed it to your camel and give it to your slaves to eat."
أنه سأل النبي ﷺ عن كسب حجام له، فنهاه عنه. فلم يزل به يكلمه حتى قال: اعلفه ناضحك، وأطعمه رقيقك.
This was narrated by Ahmad (23693), Shafii in the Musnad (2/166), Humaydi (878), and Bayhaqi (9/337), all from the hadith of Sufyan, from Zuhri, from Haram bin Saad bin Muhaysa, from his father, from Muhaysa, and he related it. Its chain of transmission is sahih.Muhammad bin Ishaq followed him in narrating from Zuhri, except that he said in it, "from Haram bin Saada bin Muhaysa bin Masud, from his father" (that is, Saada) "from his grandfather Muhaysa bin Masud," and he related the hadith. This chain confirms that when Haram bin Saad bin Muhaysa said "from his father," he meant his grandfather Muhaysa, because it was his grandfather Muhaysa who had companionship with the Prophet, not Saada. Both of these chains are connected and sahih, and although Ibn Ishaq used the form "an" (indicating a possible break), he was corroborated by another narrator.Malik narrated it in the Book of Seeking Permission (28) from Ibn Shihab, from Ibn Muhaysa Ansari, one of Banu Haritha, that he sought the permission of the Messenger of Allah ﷺ regarding the wages of the cupper, but he forbade him from it. He kept asking him and seeking his permission until he said, "Feed it to your water-carrying camel," meaning your slave. This is the version of Yahya bin Yahya Laythi, and it is a mistake with no doubt about it, for Saad bin Muhaysa had no companionship with the Prophet, so how could his son Haram have it, as Ibn Abdul-Barr said.Abu Dawud (3422) narrated it from Abdullah bin Maslama Qanabi, and Tirmidhi (1277) from Qutayba, both from Malik, from Ibn Shihab, from Ibn Muhaysa, from his father, that he sought the permission of the Messenger of Allah ﷺ, and he related it. Tirmidhi said, "from Ibn Shihab, from Ibn Muhaysa, brother of Banu Haritha, from his father, that he sought the permission of the Messenger of Allah ﷺ," and he related it.Ibn Majah (2166) narrated it through the route of Ibn Abu Dhib, from Zuhri, from Haram bin Muhaysa, from his father, that he asked the Messenger of Allah ﷺ, and he related it. His saying "from his father" means Muhaysa.These narrations strengthen what Ibn Ishaq narrated, that the incident happened to Muhaysa, with damma on the mim, fatha on the unpointed letter, and doubling of the ya, ibn Masud Khazraji, Abu Saeed Madani, though some say he was Awsi. He was younger than his brother Huwaysa, and he embraced Islam before him. Whoever says otherwise has erred.Muhaysa himself was not the cupper. Rather, the cupper was his slave boy, as mentioned in the second hadith.
